[ashokreddy nemilidinne]

I have created custom field in Jira,assigning one value for that custom field,updating issue i need to refer that custom field instead of actual issue id in Jira.

is there any to achieve this problem through Jira rest api ?

Hello,

Custom field stores values for an issue. You can not set a value for a custom field without providing an issue id.
